Editor’s
Corner
Early in September of 1984, we decided
to call our new T/S computer magazine "TIME
DESIGNS" for several reasons. One of those
reasons was not because of TIMEX (as the "X"
has obviously been dropped). At this’ same
time, many users groups had changed their
name to SINCLAIR/TIMEX (instead of the re-
verse), due to their bitter disappointment
in that company. One associate of mine even
peeled off the nameplate sticker on his 2068
and cut out the Timex name, replacing only
the "Sinclair 2068" part.
Instead, "TIME" refers to our belief
that T/S machines will be around for a _ long
"time". They are "timeless" (if you prefer)
as their technology has in no way been out-
dated. I still feel the "one-key" command
system is far superior to anything else that
I have used.
The "DESIGNS" part stems from our fond-
ness for Uncle Clive's computer "designs"...
the ZX-81, 2068, Spectrum, and now the QL.
"Designs" also is a reflection of our in-
trigue of computer-generated graphics. You
may have noticed we feature a lot of graph-
ics in the magaZine.
Welcome to Vol. 2 No. 1, our First An-
niversary Issue. Before I wrap this up, I
wish to express my gratitude. First, to you
our loyal readers. In just one year, TIME
DESIGNS has grown to be one of the largest
Timex/Sinclair publications in America. If
those first few subscribers hadn't, realized
our potential and sent in their subscription
orders [you know who you are], we probably
wouldn't be around today.
Also, I wish to thank our contributors
who have sent in their excellent materials
to be published this last year. And special
appreciation and thanks to our loyal and
dedicated advertisers also. Without them our
T/S community would be non-existent.
In closing, as editor of this magazine,
I would like to say that over the next year,
I promise to keep up-grading our content and
appearance...and that TIME DESIGNS will con-
tinue to be published. See you next issue
(in 1986)!

"T am attempting to build my own inter-
face from the 2068 to any popular printer,
for example, Epson or others. I would like
to know if this subject has been addressed
in prior issues. If not, would it be pos-
sible to request thru a user's column, some
assistance from any of your readers who per-
haps have already ‘dabbled' in this area. My
interest in computers leans toward 'do it
yourself construction', and thus my request.
Thank you for your help."

[Editor: Some may say that we have _ been
rather "skimpy" in the area of construction
projects. I vote for change right now...this
has been one of the most requested columns
lately. Anyone out there who wired up their
own printer interface, who can assist Mr.
Kern? ]
"Accolades for you! Sept/Oct '85 edi-
tion of TIME DESIGNS was the best ever...I'd
like to hear more about the 128k Spectrun.
The single-key commands of Sinclair BASIC
are not used on the QOL (I understand). Maybe
the attraction of the Spectrum has been the
use of the command key system. I have no de-
sire for a QL because of the change. I won-
der how many others feel the same way. I
also wonder how many new 2068 and 1500's
there are left with dealers? Keep up _ the
the fine work."

(ZX-81 version), featured in the Sept./Oct.
issue of TIME DESIGNS.
now received the first two
issues (#5 & #6) of my subscription, and I
want to congradulate you for a very fine
magazine. Many of us are first time users,
and self-taught, and far from any known user
groups; so the arrival of each issue is an
eagerly anticipated event. The suggestion
submitted by Mr. Russell Ochoki to publish a
column of programming tips and useful short
programs certainly receives my endorsement.
I would be particularly interested in the
use of system calls. (I have tried in vain
to obtain a copy of the T/S 2068 Technical
Manual.) For example, it took me quite some
time to figure out how to BEEP from machine
language. (SOUND was easy.) I am happy to

U.S. QL - $299
Sinclair's 32-bit micro, the QL, now
has a suggested retail sticker of $299 U.S.
dollars. Not only is it much more affordable
but also easier to obtain. In a generous
gesture, Nigel Searle of Sinclair Research
has offered the QOL with incentitives to T/S
dealers here in the States. At this writing,
seven companies have contacted TIME DESIGNS
to announce that they will be handling the
$299 OL. They are: Curry Computer, EMC (The
English Micro Connection), Knighted Com-
puters, Ramex International, RMG Enterprises
Sunset Electronics, and Zebra System, Inc.
The new QOL price tag is a follow-up to
the half price cut in Europe last September.
Sinclair is preparing for what could be a
"make-or-break" Christmas selling season in
Great Britain.
While the OL emerged upon the home com-
puter market with flair, it has been moving
Slowly in sales. Sinclair claims that the
new price reduction is a result of reduced
manufacturing costs, and major savings from
a substantial increase in manufacturing vol-
ume (based on current sales "commitments" ).
Industry-watchers noted that the QOL price
cut came three days after the announced re-
lease of a competitor's new computer...the
Amstrad PCW8526.

feet for the time being,
debt rescheduling
is still on its
following the major
with Barclays Bank and
other creditors. Sub-contractors Thorn EMI,
Timex Corp. and AB Electronic Products were
all agreeable to the terms. These companies
assemble Sinclair's computers in contracted
factories. Sir Clive, who's lack of manage-
ment skills have been well-publicized, has
placed a new management team in control of
Sinclair Research's future direction.
The QL with its $299 (complete) price
should move quite a few units here in the
States. A lot of new software is available
from the U.K. presently, with hundreds of
new titles currently being developed. Sin-
clair has just authorized the production of
a new floppy disc system (3 inch drives),
that should be out sometime early next year.
optional private listening),
128k SPECTRUM
The Sinclair 128k Spectrum in no longer
rumor, but fact. In September at a home com-
puter and electronics show in London, Sin-
Clair unveiled their new machine, the last
few days of the show. Suprisingly, the 128k
Spectrum resembles the T/S 2068 except for
the QOL-type black case. It utilizes the 2068
bank-switching, three video modes, three-
channel sound chip, and built-in joystick
ports. Reportedly it is 100% compatible with
all software for older Spectrum models.
As we went to press, the 128k Spectrum
was already available in Spain. However, it
it is expected to be in the English _ shops
after the first of the year. A spokesperson
for Sinclair (U.S.):-told TIME DESIGNS that
there are no plans to market the 128k Spec-
trum in America. Although Bob Dyl of the
English Micro Connection announced plans to
carry it, when supplys are made available.
POCKET TV PERFORMS WELL
The new Sinclair Pocket TV is truly an
amazing piece of high-technology. Last week,
TIME DESIGNS obtained a sample unit for re-
view from Sinclair Research. The Pocket TV
is a compact iittie unit 15 1/2" -x.3.-1/2224
1 1/4") with a black plastic case. It util-
izes circuit miniaturization extensively. It
is powered by Polaroid's unique 6v (flat)
Lithium battery. This battery. is rated for
15 hours (total) life. However, an external
DC supply jack is also provided. The Pocket
TV comes complete with a tiny earphone (for
and a smartly-
styled velvetine carrying pouch. Suggested
retail price is $100.
Unlike most standard TV's, where the
picture image is "Shot" from the rear of the
set to the front screen surface, the Pocket
TV's screen is absolutely "flat", and the
viewer peers in at the screen thru a plastic
fresnel lens. The viewing area iS aprox. 1
and 1/2 x 1 inch. The Pocket TV is’ tuned
by turning a small thumb-wheel (moving a
4
needle accross a calibrated dial). VHF and
UHF are selected by a switch. The built-in
18 1/2" telescoping antenna pulls the TV
Stations in.
In a side-by-side comparison test with
the Sony Watchman, the Sinclair Pocket TV
picture clarity was just as good, if not a
little better. Not to mention that the Sony
retails for twice the price of a Sinclair.
The Pocket TV received every available VHF
and UHF station in the high-signal strength
area. When tested in the "fringe" area, it
demonstrated good sensitivity, pulling in
about half of the available stations...with
fairly decent reception. The volume control
on the unit can be adjusted from quiet to
Suprisingly loud levels.
If you would like to own one
Clive's latest electronic wonders,
certainly a "conversation" piece.
tical uses for the TV are possible such as
private home viewing, camping, or _ sports
events. If interested, some T/S dealers have
the Sinclair Pocket TV available.

Everyone enjoys looking at the stars on
a starry night even when they do not
consider themselves amateur astronomers. A
standard pair of binoculars can reveal some
breathtaking sights in the night sky. They
can show Jupiter and between two and four of
its moons...including the forbidden Europa
2010 fans! Jupiter is quite a sight all
summer long. Halley's comet is coming and
will be easy to spot in those same
binoculars by November, if one knows where
to look.
But if everyone feels as I do, the
heavens can be a little confusing when it
comes down to finding things. If one does
not know the constellations, or has no idea
where to look to find anything less obvious
than the full moon, then I may have just the
remedy. The 2068 can direct us, using the
accompanying program listing.
Up until now, looking things up in an
astronomical reference only provided some
coordinates given as "Right Ascension" and
"Declination" or "RA" and "Dec". These
strange figures are for aiming telescopes
accurately, but are generally meaningless to
the casual observer. The 2068 can make sense
out of most anything, and such is the case
with RA and Dec. The computer can convert
these values into an easier to follow set of
horizontal and vertical coordinates called
altitude and azimuth.
Altitude indicates the relative height
in the sky being zero at the horizon and
progressing to 90, directly over-head.
Simple enough. Azimuth is just as easy.
Remember a compass with north, east, south,
and west? Azimuth follows the compass clock-
wise with zero as north, 90 as east, 180 as
south, and so on to 360 (north again). Even
if numbers zero to 360 are confusing, the
program prints out the compass directions
too.
The program spits out values by time of
day for which compass direction (azimuth) to
look and how high off the horizon (altitude)
to look, to find just what we are searching
for. By using any set of RA and Dec values
2068 GAZER’S GUIDE
CRETE aR Ae BHT
by Paul Bingham
in an astronomy book or from magazines like
ASTRONOMY or SKY AND TELESCOPE, we can
easily find any object in the sky any time
for any date. Our program and the 2068
handle all the calculating...all we do is
look where it indicates and enjoy!
PROGRAM NOTES: The program is designed to be
Simple and straight forward. One - can
naturally alter it to suit one's taste, but
lines 30 thru 115 are the program's core,
and should be entered as is.
As the program listing stands now, "o"
and "L" for longitude and latitude in line 5
are set for my location. Someone in the
local liabrary map room can help with these
values if available nowhere else. The factor
"kK" in line 5 is set for 1985. Values for
[the years] '86 thru '89 are: 6.6241,
6.6081, 6.5921, 6.6419 respectively. The
value "v" is the time zone displacement. The
west coast is 8, the east coast is 5, my
zone in Arizona is 7.
RA and Dec are always listed in hours-
minutes-seconds fashion. Rounding to the
nearest hour value is generally accurate
enough. The program will accept hour values
with decimal input, if real accuracy is re-
quired. One must remember to enter a minus
sign if one is listed with the RA or Dec
value. 5 oe
The 24 time system is required by the
program. This is familiar to most everyone,
but in case one is rusty...midnight is zero.
The value increases by one, each hour thru
noon (12). Then 1:00pm becomes 13 and so on
to 11:00pm (23). Figure A for Jupiter will
show that even fractions of the hour are
accepted.
The program will indicate a minus
altitude value for any object below the
horizon. Objects near due south, or directly
over-head sometimes give less accurate
results until the object moves. The
remainder of the program needs no
explanation to run.

How appropriate it was to sit down in
front of this program the day Shuttle
Mission 51-D was launched. Senator Garn flew
on 51-D, and so did Rhea Seddon, the only
astronaut from my home town of Memphis
("Cosmic Rhea" we call her).
Whin I look at a new piece of software,
my usual approach is to determine first how
user-friendly the program is. If I can get
satisfactory results from the program with-
out relying on the documentation, then I
judge it to be user-friendly. I have had to
revise my definition of satisfactory re-
sults. Shuttle Designer is user-friendly,
but my approach toward mastery of the pro-
gram has been asymptotic.
"Satisfactory" means getting the rocket
you design to put the assigned payload into
a suborbital trajectory at the correct
velocity before it runs out of fuel. If you
Succeed, then you are given an "access"
code. The code is necessary to continue so
that you can design a more complicated
rocket. A second success gives you a final
access code. You have graduated to the point
at which you are qualified to design a Space
Shuttle.
Help is available. First comes an
elaborate tutorial on single and multistage
rockets, liquid and solid fuels, principles
of propulsion, payload considerations, and
expected performance. Finally, you get to
see the programs which accept user input to
design a rocket based on the tutorial infor-
mation.
A dozen or so graphic diagrams are dis-—
played. If you have a printer, several
Charts summarizing characteristics can be
printed out to save back-tracking or hand-
copying important review information.
Your patience and perseverance are re-
warded by being given opportunity to design
your own rocket. You determine how much and
what type of propellant to use, how fast the
fuel consumption rate should be, and how
large a rocket to use, to carry the fuel,
crew, and payload.

If your design has a major flaw, a
member of your project team lets you know.
This courtesy saves you much embarrassment
on the launch pad. If the design doesn't
look too bad, you are invited to witness the
launch.
A twenty-five second countdown begins.
Sometimes it is interrupted to correct or
analyze a last minute problem. Finally, the
launch takes place. The rocket slowly rises

(actually, the launch tower slowly dis-
appears off the bottom of the screen).
The view changes to an Earth chord,
with the trajectory of your rocket traced
above it. Readouts below the diagram show
how rapidly the rocket is accelerating, and
how much time has elapsed since ignition.
From this point, you will see either the
announcement that your rocket is out of fuel
or that your design has been successful. You
are shown the projected point of impact,
successful or not.
Shuttle Designer helps the user
appreciate the planning that has gone into
the American space program. It has helped me
realize that I can't absorb everything that
must be known about rocketry in one hour.
But just give me a few more days...
I thought some video games I've played
were addictive! Shuttle Designer is no
"space invaders" game. It is however, an
absorbing educational tool for individual or
classroom use.

At the end of Part One of this article,
published in the SEPTEMBER/OCTOBER issue, we
emerged, unscathed by any "BUGS" from the
upper RAM jungle onto the plateau of the
safe area. We now descend into the lower RAM
jungle where a giant bug lives, ready to de-
vour the unwary. A map of the lower RAM
jungle during its four major "Seasons" is
illustrated in Figure No.1. Note the change
in the "Landmarks" (addresses in the system
variables) due to the expansion or contrac-
tion of the different areas during the dif-
ferent seasons. Just as all data below E__
LINE is saved when recording the program on
tape or other media, so must this data be
saved whenever an area iS expanded or con-
tracted. This is done by actually moving the
block of data that exists from the point of
expansion or contraction to E LINE (in-
clusive) moving it up or down in memory and
writing over whatever existed in these _ ad-
dresses. All data in the system variables is
adjusted to the new addresses.
Now that you have familiarized your-
self with the map, I can proceed with some
definitions. The minimum address to which
you can actually set RAMTOP and the program
will run, is the address of the top of the
Calculator Stack (C Stack) during the ex-
ecution of the program, plus the number of
bytes in the combined GOSUB Stack (GS Stack)
and Machine Stack (M Stack) during execution
of the program, plus the 36 bytes of Spare
Space required to avoid getting an "Out of
Memory" error code. The number of bytes in
the combined GS and M Stacks during the ex-
ecution of the program is found by subtract-
ing the upper limit of the safe area, de-
termined, as we did in part one of this
article, from the actual value of RAMTOP.
The lower limit of the safe (from _ the
RUN command) area is the address+1 of the
ADVENTURES IN THE RAM JUNGLE
AND OTHER MYSTERIES
(PART TWO)

program. The lower limit of the safe (fron
any other direct command) area is the ad-
dresst+1 of the top of the C Stack after the
_ program execution, and upon entry of the
direct command. You can see from the _ def-
inition that the lower limit of the safe
area is a floating value which depends’ upon
what direct command will be entered into the
computer after program execution.
Entering a direct command can have two
effects on.the-C Stack. -The first is to
access work space which moves the C Stack up
in memory. The second possible effect is to
expand the C Stack. Can we determine how far
a direct command moves the bottom of the C
Stack? It should move the C Stack the same
amount as there are bytes in the same com-
mand, entered as a program line, less four
bytes containing the line number and the
number of bytes in the command itself. To
find the number of bytes in a; direct com-
mand, enter it into the computer with a line
number. Then enter the direct commands PRINT
PEEK 16511 to find the low byte and PRINT
PEEK 16512 to find the high byte -.of the
length of the command. For example, enter
the double PRINT PEEK n command with a line
number:
40 PRINT PEEK 16419+256*PEEK 1
6411 |
Peeking 16511 and then 16512 you should _ get
37 for an answer. Now enter the single PRINT
PEEK n command with the same line number:

If you have more than 16k RAM, set RAMTOP
to 32768 by poking 16388,0 and 16389,128.
Then press NEW and ENTER.

I will call this Program One in the rest of
the article. After saving the program, enter
NEW, rewind the tape, load the program and
enter RUN. The program will print the value
17654 on the screen forty-eight times. Since
we will be doing things to the program that
could change the location of the bottom of
the M Stack, we must find the upper limit of
the safe area first. Proceeding as we did in
Part One of this article, peek the addresses
under RAMTOP-50 and working down. in memory
until you find only zeros. This occurs at
address 32715. Therefore the bottom of the M
Stack is 32716 and the upper limit of the
safe area is 32715 for this program.
If we peek STKEND using the direct
double peek command:
PRINT PEEK 16412+256%PEEK 16413
and then peek STKBOT (bottom of the C Stack)
using the direct double peek command:
PRINT PEEK 16419+256*PEEK 16411
we get the same value, 17435. This is be-
_cause the C Stack is collapsed by the ROM
routines at the end of the program execu-
tion. But is 17435 the actual location of
the bottom of the C Stack during program
execution? To find out, change line 20 of
Program One to read:
20 PRINT PEEK 16419+256*PEEK 1
64115" tT
3
Now RUN the program and it will print the
value 17398 on the screen forty-eight times.
If you peek STKEND and STKBOT using direct
double peek commands, you will again get
17435 which is a difference of 37 for the
double peek commands. Now enter the follow-
ing direct single peek commands:

this prints 68
and 4+256*68=17412 which is the difference
of 14 from 17398. You get these differences
from the 17398 because a direct command will
access work space, moving the collapsed C
Stack up in memory by resetting the system
variables STKBOT and STKEND. The expanding
work space and expanding C Stack write over
whatever was in the addresses above E_ LINE.
After the direct command has been executed,
the C Stack is collapsed and moved back down
to — LINE merely by resetting the system
variables of the C Stack to the address of
E LINE. The address immediately below E __
LINE always contains the decimal value 128
(80h). The addresses occupied by the ex-
panded C Stack are then cleared by placing
zeros into them, precluding us from
where the top of the C Stack was during ex-
pansion. Referring to Figure No. 1, you can
see the same thing happens to the spare
Space the expanded portion of the C Stack
occupied during the execution of the _ pro-
gram. Foiled by the Wicked Wizard of ROM.

Program One.
you will get 128. Now enter CLEAR which will
move E LINE down by deleting the variable
N. Delete the program lines 30, 10 and 20
which will move E_ LINE (and the collapsed C
Stack) even further down in memory, so that
entering another peek command will not write
over where the work space and C Stack were
during the peek to 17397. Now peek the _ ad-
dress from where E LINE was’ immediately
after running the program (17398), upwards
in memory. After address 17412 you will find
only zeros. If you wish, you can repeat’ the
procedure starting with entering NEW and
using the direct double peek command. You
will find nothing but zeros above address
17435. Since the peek commands contain nu-
merical values which must be changed into
floating point, using C Stack, then we know
that the expanded portion of the C Stack was
wiped out with zeros after the command was
executed.
When we ran Program One, we found that
17654 was the address stored in STKEND= dur-
ing the execution of the program. Is this
the actual top of the C Stack during the
execution of the program? To find out, we
must lay down some sticky fly-paper to trap
the top of the C Stack. Press NEW and ENTER.
Then type in the following:
seeing

32 NEXT N
DO NOT RUN YET. Save this program on tape
using SAVE "TWO". I will call this Program
Two in the rest of this article. Run _ the
program which will lay down the fly-paper

This occurs at address 17417. Therefore the
lower limit of the safe (from RUN) area is
17418.

wards in memory, you will find the values
that were in the work space up to the 118 at

in address 17412 which is the bottom byte of
the C Stack. From 17413 to the top of the C

Stack at 17431 you will find only zeros. At
address 17432 you will find the first
You will find only fives in the address a-
bove that and on up to 17654. Therefore the
lower limit of the safe (from PRINT PEEK n)
is 17432. Proceeding in a similar manner,
you will find that the lower limit of the

is less than 19712, we can set RAMTOP to
this value and the program will run. The
reason you do not have to add 36 if RAMTOP

Compusa, Apple, Atari, and Commodore) trans-

International claims, because not all of the
disk bits are data bytes. About 20% of them
are header information (where you are on the
disk), CRC Data (= Cyclic Redundancy Check

keeping information the controller needs. So
use a real
the fastest you can get the bytes into the
system is maybe 25k/sec. +/- maybe 15% de-
pending on how many sectors/track (lots of
sectors = lots of headers). Now the question
arises, what are you going to do with those
bytes and how fast? In our system (AERCO),
the fastest mode is .SCR. In that case, the
first 2/3 of a screen are fiiled directly
from the disk, then a 6Ms. interval to step

probably .BAS. I really haven't done any
measurements, but I would guess that it
might range pretty close to what you

the first second of any disk operation is
"dead time" waiting for the drive motor to
reach operating speed (300 R.P.M.)."

DISK DRIVE
SYSTEM
FOR THE 2068
Review by
John Gaddis
In the
beginning, there was_- the
cassette. And as Timex began to tell people
of their new powerful color computer, the
only thing that stopped it from being
compared to other computers in its class,
was the lack of a fast mass storage system.
But, people like myself bought this new com-
puter anyway, because it was the natural
progression from the ZX-8l1. And we waited
for the mass storage devices that were
promised. Well, I am here to tell you that
the wait 1S over.
Unless you have been out of the country
for the past year, I am sure that you have
heard about the Timex Portugal Disk Drive
System that was made in Europe and might be
sold here in the United States. For a time,
it seemed that this D.D. system would not be
sold here. But thanks to some hard work by
Zebra Systems Inc., the drives are here.
I received my drive about three weeks
You may be interested in looking in the
COMPUTER SHOPPER magazine for your own disc
drives and cases [if you are considering the
Aerco interface]. They seem to list some of
the best prices around. The Aerco FD-68 Disc
Drive System is available from: AERCO, Box
18093, Austin, -TX, 78760. Cost:. for inter-
face alone is $199.00, for the complete unit
(interface board, single drive, case and
power supply) is $400. I will report in up-
coming issues of Time Designs on any further
improvements to the disc
drive interface.
seperate styrofoam boxes. Once you open
these boxes you will find an interface that
plugs into the back of the computer buss
(with a Spectrum Buss Adapter or "Twister",
which Zebra supplies), a D.D. Controller, a
Power Supply, and the Disk Drive itself.
Fach unit is about 4.5"W x 2"H x 6"D. They
are the same silver color that the 2068 com-
puter is painted with.
Connecting the power supply to the con-
troller and the disk drive, and the ribbon
cable of the controller to the drive, is ex-
plained in detail in the system manual. The
documentation that is supplied with the
system is by far the best and most easiest
to understand of any documentation I've seen
for a Timex related product. The document-
tation and "ease of use" make this the best
mass storage device on the market for the
T/S 2068.
Once you have the system set up, the
first thing that catches your eye, is the
use of the 3 inch floppy disk. They are
double-sided and double-density (although
you can only write to one side at a time)
and hold 360k of information. Also you will
notice that the disks are much harder, and
able to take abuse better than 5 1/4 inch
floppies.
As soon as you get the system up and
running, you will see a new copyright
message along with the Sinclair and Timex
messages. It will say "TOS 1985". Though it
does not say it in the manual, this stands
for Timex Operation System. Once I started
to use it, I found it to be the most user
friendly, and most powerful operating system
ago. The system itself comes in_ three 1 és

cased in plastic.

sur face.
of any "under $1000" computer on the market
today...and belive me, I have used them all.
You will notice, if you use the PRINT
FREE command that the operating system uses
none of the computer's memory. That is be-
cause the TOS is in ROM in the controller.
Not only does the controller have its own
ROM, it also has its own Z80A C.P.U., as
well as its own RAM. It is correct to say,
that the D.D. system is a seperate computer
to the 2068.
As you start to use the drives, you
will find that the only change you have to
make in loading and saving files is to use a
"xk" after the command. Instead of LOAD and
SAVE, it's LOAD * and SAVE *. After reading
that one sentence, you can now convert and
use most of the programs you now own. There
is the CAT * command to display the disks
contents, FORMAT * to prepare the disk for
use, ERASE * to erase files on disk. As a
matter of fact, all the commands that you
used to look at with great curiosity at the
top of the keyboard are now up to good use.
As the manual leads you step by step
through the operating system, the ease of
using this disk system becomes apparent. The
TOS uses a "tree" structure that utilizes
many directories on one disk. These direc-
tories are the "roots" that branch out to
related files. The manual goes into this in
detail in chapter 4.
The floppy disk [supplied with the
drive] comes with some demo's and utilities
that are worth noting. There are games and
displays in the FUN directory. MATHS and
FILING directories are good as well. It is
the UTIL (or utilities) directory that is
the most interesting. First, in order to
take advantage of the two (yes two) RS-232C
connectors on the back of the controller,
there are programs to send and receive Saiz
have noticed.
(via modem or direct hook-up), and a program
to run a printer. A great program is one
that will copy an entire disk to another
disk as a back-up. Take my word for it that
you will use this program often.
A description of everything this disk
operating system can do would take much more
room than I have here. There are methods of
creating, erasing, protecting, copying and
renaming files, as well as an extensive
"help" file which will answer any question
you may have.
Being a member of the Long Island Sin-
clair/Timex (L.I.S.T) group [in New York] as
well as a person who uses computers at work,
I have seen a lot of disk operating systems.
I have yet to see one that offers so much to
the user, including the systems that are out
there now for the 2068.
There are some minor short-comings I
One is that the power supply
runs a little too hot. Another is that there
is no feed through on the interface for you
to connect other peripherals. On that last
one though, Zebra Systems Inc. is in the
process of making a "Super Twister" [or
properly named Zebra Interface] that will
have two feed-throughs, as well as an RGB
connection and a [optional] Spectrum emu-
lator. This twister will be ready soon.
I have no complaints at all about the
way these drives operate. I now load TASWORD
in seconds (in a little less than 7 seconds)
instead of minutes. But I also have "random
access". This allows me to write software
that is not dependent on the computers mem-
ory. This is because you can use the D.D. to
develop a "DISK RAM" system. What this does
is it allows you to use the disk rather than
the computers memory to store all your
variables. In that way, you can have over
65,000 names in an address file!
The Author's sys
The separate system components can be seperated as
in this photo, or stacked upright.
In summation, it took me a long time to
decide which mass storage system I would
buy. I feel that by waiting for the
Portuguese [Timex] Disk Drives to become
available, the wait was worth it. And what
with rumors of C/PM compatability on the
horizon, there seems to be no limits to what
our Timex/Sinclair 2068 can do. In my mind,
the Zebra Floppy Disk Drive System was and
is the best mass storage system, bar none.

OBSTACLE RUN is a game for one player,
or several players by comparing scores. The
object is to move your piece, a heavy circle
(that initially appears in the upper left
corner of the screen), around the serpentine
track, to the finish line, as quickly as
possible. The piece can be moved in any of
eight directions by the cluster of keys in
the lower left of the keyboard, the Q,W,E,A,
D,Z,X, and C keys.
The score is made up of three weighted
elements:
(a) How many steps are taken.
(b) how many obstacles "*" are struck
(they cannot always be avoided).
(c) How much time is taken.
The object is to score as low as_ pos-
Sible. Timing starts as soon as the player's
piece appears.
This game was devised to illustrate the
short-coming of most joysticks. Although the
typical joystick can produce diagonal mo-
tion, it does so only after a lag caused by
moving vertically or horizontally first.

OBSTACLE RUN

the closing of two of it's internal elec-
trical contacts, and they generally do not
close simultaneously. Hence the usual joy-
stick gives a vertical or horizontal step
before moving the piece diagonally. In this
game such a drawback can be disastrous as
the game ends by disqualification if any of
the barriers are struck, or if the piece
goes out of bounds.
Why use diagonal steps? In this game it
can mean a much lower score. One diagonal
step counts less than a vertical step plus a
horizontal step to reach the same block.

ZPRINT—- 80
Review by
Michael E. Carver
If you own a full-size dot matrix
printer and a Centronics interface, you can
now produce full-page graphic screen dumps.
You will also be able to faithfully repro-
duce your color artwork in shades of gray,
thanks to Zebra Systems Inc. "ZPRINT-80".
Zprint-80 is a printer support package
for the T/S 2068 and Spectrum computers,
which will reproduce full-page gray-scale
dumps of color screens. I received an
advance copy of this software {version 1.2)
to test with my Aerco printer interface and
a Mannesmann Tally Spirit-80 printer. This
review will be based only on this config-
uration. I was informed by Zebra that there
were a few bugs discovered in this edition
and that they were corrected before shipment
of any orders. They also stated that if any
more problems occur, they will gladly re-
place any faulty software with a corrected
update. If only other software companiew
felt this responsibility to their customers!
(Note: See insert for the interfaces and
printers supported by package)
The cassette contains a Timex version
on one side and a Spectrum version on the
9
ZPRINT-80's grey scale representing eight colors. Picture to the right
was "painted" by the Author using the new Spectrum program, "The Art-
ist". It was printed on a full sheet using ZPRINT-80 (with "custom"
changes), then reduced photographically.
flip side. I had no trouble loading either
Side the first time. The program loads in
two parts. The first will prompt you for the
address to place the driver program (all
machine code). It may be placed at either
64000 or 27000. The latter is specifically
designed for use with programs such as Zeus
Assembler/Disassembler. Instructions are
provided in the manual on merging Zprint
with Zeus and your own programs. The main
code is then loaded. Next you are to choose
the brand of printer to be driven and
through which interface, width (a max. of
136 characters), and whether a line feed
needs to be sent to your printer. The pro-
gram will then save this "customized" ver-
Sion to tape for future use.
Two types of screen dumps are available
through Zprint. Both are accessed by RANDOM-
IZE USR calls. The printer is put into dual-
density graphic mode for these dumps and
then reset to power-up state after com-
pletion. The first is equal to the copy
routine and dumps sent to the T/S 2040
printer. The size is the same and only set
pixels (ink) are printed. Normally, this
dump is printed in the center of the paper,
but any column may be chosen for the left-
hand margin. The second will produce a large
scale picture on an 8 1/2 x 11 sheet of
paper, reproducing all colors, ink or paper,
in shades of gray. This program will not
produce different shades for BRIGHT (see
example). This picture is printed sideways
on the paper. In both versions, all 24 lines
of the screen are printed. The graduation of
color-scale is very good; however, on my
Spirit 80 the proportions of the pictures
were distorted. The full page picture was
stretched out on the sides, and small blank
lines were visible between each line of
Changing the program's line spacing com-
mand. The normal screen dump was compressed
_length-ways. Again I was able to compensate
by changing the size of line spacing in the
code. Hopefully, these will be fixed in the
new version. (NOTE: Aerco's copy routine is
totally inadequate for graphic dumps. Large
blank lines were left between each line. I
had to write a machine code patch in order
to obtain a decent graphic screen dump.
Aerco never responded to my inguiry on how
to remedy this problem.) Painting a full-
page masterpiece is not quick, but Zebra
claims that their's is faster than Tascopy
(Zprint-80 in 5 min. vs. Tascopy's 9 min.).
Zprint is also a full-size printer
driver, supporting both LPRINT and LLIST.
(NOTE: Upon loading Zprint, the contents of
my first LPRINT was never sent to _ the
printer. Zebra assured me that this problem
has been fixed.) I find that Zprint is
easier to use and more dependable than the
driver I received with my Aerco interface.
Zprint works in tandem with the 2040 printer
routines contained in ROM. This should allow
Zprint to be compatible with more software
than some other drivers. I can even use
Zprint with Vu-File, if I leave at least
1500 bytes unused in the data file. There is
no need to POKE addresses before choosing
LLIST or LPRINT when using Zprint. I am em-
barrassed to tell how many sheets of paper I
have wasted with Aerco's software, because I
forgot one precious POKE before attempting a
listing. You can easily toggle back and
forth between full-size and 2040 printer by
RANDOMIZE USR commands. With Zprint, if your
printer goes off-line (out of paper, error,
dog bit through power cord) Zprint will not
fail or break-out into BASIC. Once you have
fixed the printer's problem and switch on
print. I was able to compensate for this by 20
line, printing will continue where it left
off. Aerco's software would break into BASIC
and at times be unable to continue print-
ing after the printer was brought back up.
LLIST'ings produced with Zprint are consis-—
tant with the screen and the 2040 printer,
if width is set to 32 (this is changed by
POKE'ing (base + 12), width: RANDOMIZE USR
(base) ). Even when my Aerco software was set
at 32 characters, my listings still did not
correspond with the sceen in spacing.
I feel that Zprint has done an ex-
cellent job in cramming so much into a small
package (1300 bytes compared to Aerco's 1111
bytes). If you are looking for a means to
make enlarged color graphic screen dumps or
an improved printer driver, give Zprint a
try. (NOTE: I would like to state, that my
recommendation is based on past experience
with Zebra and their fast response to prob-
that they appear sincere about
lems. Also,
either, delivering a product that will per-
form, or gladly refunding your money, if
they cannot correct the problem.) You may

VIEWORD MAILIST FORMAIL
Reviewed by
Tim Woods
Several months ago I received a_ three-
piece software "package" for review from Jim
Clatfelter (3361 Sand Ridge Rd., Placer-
ville, CA 95667). VIEWord, MAIList, and
FORMail are for the T/S 2068, and the three
title package is priced at $25 (postage
cluded). My reason for the delay in writing
this software review, is that I wanted to
really put these programs to use and get to
know their features, instead of just jotting
down a few comments from a hasty evaluation.
VIEWord, MAIList, and FORMail are util-
ity programs that would be most suited for
the small business environment or personal
home computing. VIEWord is an interesting
(but easy-to-use) word processor. MAIList,
as the name implies, is an address manager,
and FORMail is a utility that uses files
from both VIEWord and MAIList, to print for-
mal type letters. My initial impression of
in-
this package, is the over-all professional
appearance it has. Not just the labeling or
instruction
sheets, but in the programs
themselves. Obviously Mr. Clatfelter has
spent a good deal of time in developing and
programming them.
To give you a little background, the
programs are mainly written in BASIC, except
for a print-driver routine. Output can be
sent to either the T/S 2040 printer, or toa
full size printer using the Aerco Centronics
interface (the bytes for the Aérco interface
have already been programmed ‘in). I feel
that it would be quite easy to customize
the programs for your own printer interface
such as the Tasman.
One very striking feature of this soft-
ware package, is that it is "integrated". A
feature found on much costlier :.software for
computers like IBM PC. In other words,
mands and procedures found on one _ program
would operate exactly the same in the other
programs. Once you have learned VIEWord (for
com-
example), working with MAIList is a _ breezZe.
As a word processor, VIEWord is’ much
simpler to use (for first time users), than
say MSCRIPT. Yet it is much more_ sophisti-
cated than some of those "what you type is
what you get" word processors. You can set
your line-length to either 32 or 64 col. To
use the extensive editing features from the
menu, just enter a key-letter on the first
command line. Going back and fixing up a
mistake later on is handled differently than
what

never

on most word processors. You indicate
the mistake is, retype what should be
and the computer compares the two and
serts the new information. The user
operates the cursor or delete key in
operation. Other features include: block cut
and paste, tabs, centering, page numbering,
embedded printer control codes, and a type of
word-wrapping. The only two complaints that
I have are, it would be nice if the word
wrap feature was automatic, and there is no
right column justification.
MAIList is a real gem. I have seen the
gamut of address managers for 2068 and Spec-
trum computers. None of them are as compre-
hensive as this one. Along with the normal
data entry, there is also record keeping of
telephone numbers, catagories like birthdays
or special filing codes, a section to put a
Special comment that can be printed on _ the
label, or not if the user so

file. Printing can be done on
label sheets, or a "master list"
paper. A label file can be ordered by zip
code, last name, or phone number. The time
it took to order a full file was about two
minutes. All of the extensive editing and
searching features that VIEWord has, are in
MAIList also.

load-
ed into FORMail, and then other information
can be introduced like a header date and a
Salutation. Then it is all sent to a printer
which makes a nice note with custom name and
address on each letter.
Although the programs were in BASIC,
they operated faster than I expected. Being
in BASIC also allows for customizing to suit
a particular need.
I think that you would find this soft-
ware package to be versatile and comfortable
to work with. At $25, that is only $8.33 per
program...a very good deal. If you do happen
to take Mr. Clatfelter up on this "deal", I
think that you would be suprised at how much
you get...as I was.

MMMM =D'KTRONICS SPEECH SYNTHESIZER
Review by
Michael E. Carver
You have your computer hooked up to
your CRT, your line printer plugged in, and
the computer is emitting beeps or, perhaps,
even music, but...if only it could speak.
Oh, the stories it would tell. Thanks to
Dk'tronics, your computer can keep you up
all night with amazing tales.
Dk'tronics Speech Synthesizer for the
Sinclair Spectrum is available in the U.S.
from DAMCO. If you have a T/S 2068 and a
"twister" allowing Spectrum hardware to be
plugged onto your edge connector, Dk'tronics
synthesizer can make your computer speak up.
The voice produced is mechanical, more like
a Buck Rogers robot or a Dalek (for you Dr.
Who fans), and not lyrical or as human as
HAL's in 2001: A Space Odyssey.
This package consists of hardware and
software. Included is an interface con-
taining the synthesizer and an amplifier,
plus an external 4-inch speaker. The inter-
face is 4" x 2 1/4" x 3/4" and is enclosed
in a black plastic case with full through-
buss connector out the rear. The interface
case also has a volume control knob and a
standard earphone jack for hooking the in-
terface to the speaker, or an audio system/
tape recorder.
The brain (or voice) of this interface
is General Instrument's SP-256 synthesizer,
which contains an allophone library in ROM.
There are 59 different speech’ patterns (or
allophones) and 5 set pauses stored in this
library. Words are created by combining
these allophones into specified patterns
(see table 1).
The synthesizer can be operated in four
different modes. The first requires no
special software. The interface is accessed
through BASIC, using the OUT command to send
an allophone code to port 127 (see listing
1}
To use the remaining modes, the accom-—
panying software must be loaded. This soft-
ware 1S approximately 4.7k of machine code
and can be located anywhere in RAM. The
positioning of this software is done by the
loading routine, after specifying the de-
Sired location. The second mode is similar
to the first in that you must look up each
allophone, but is sent to the synthesizer in
an LPRINT statement (see listing 2).
Modes three and four are the easiest to
use as they are text-to-speech modes. About
3.5k of the program contains a table of
English rules along with some of the many
exceptions (see listing 3 & 4). Modes 3 and
4 are “interrupt driven", returning control
back to the computer while the synthesizer
continues to speak. Mode three's text buffer
will only hold 100 characters. Any LPRINT
statement with more than 100 characters will
be truncated, loosing extra text. I was un-
able to cause any lost text in mode four.
Since there are more exceptions than
rules in the English language, at times it
will be necessary to mispell a word to
achieve a recognizable pronunciation, (i.e.
Silicon = silickon). It is not possible to
produce inflection patterns with this syn-
thesizer, but there are sixteen speeds for
Speech output. There are a few "bugs" in
this part of the software which cause some
awkward pronunciations. The text-to-speech
software changes the "ahh" sound to "or",
giving the computer a strange Bostonian
accent. Also, the "a" in such words as "cat"
is pronounced like "caught". It is sometimes
neccesary to combine the "feed" feature with
either modes three or four to produce ac-
ceptable speech. (NOTE: Modes 1-3 will work
with your computer in Timex ROM select)
The manual, accompanying the unit, is
very helpful in getting one started. There
is a section on accessing the software via
calls to its various routines, to help those
who enjoy writing machine code. Anyone
should be able to teach their computer to
speak with this unit, by simply following
the easy steps laid out in the manual.
If you are interested in speech syn-
thesis and will settle for a "mechanical
voice", I feel that Dk'tronics unit is a
good buy for the price. It was very easy for
me to add speech to a BASIC Star Trek game,
with only minor changes to PRINT commands.
With a little effort, a talking machine
could be constructed for those with physical
disabilities.

FINALLY THE TS2068 COMES OF AGE!
ZEBRA FLOPPY DISK DRIVES
ONLY 3349.95
The addition of disk drives
to the TS2068 creates an
immensely powerful system,
and T.O.S., the disk operating
system especially developed for
ZEBRA SYSTEMS gives you
the power from within your
BASIC program that you have |
always wanted, but never |
believed would be available...
The secret of this disk
system lies in its sophisticated
controller, which is a seperate
computer which has it’s own _ .
4Mhz Z80A Central Processor, as well as its own 16k internal memory sa Final fouliet
facilities. In this controller resides the Advanced T.O.S. Operating System. T.O.S. allows
full control over disk access including saving and loading of programs, and Random or
Sequential file handling of data. The versatility of T.O.S. enables random—access database
programs to be written, which is not possible with any other TS2068 mass storage
system. T.O.S. supports an MSDOS-—like tree directory structure with named diskettes,
named files (8 character names plus a 3 character file extension) with attributes
(protection and catalog), pathnames, wildcard file selection and up to 16 file or serial
channels open at the same time. New commands added to Timex BASIC by T.O.S.
include: CAT*, LOAD*, SAVE*, OPEN*, PRINT*, INPUT*, LIST*, RESTORE’,
MERGE*, GOTO*, GOSUB*, DRAW*, CLOSE*, FORMAT*, ERASE*, LET*, ATTR*,
MOVE*. Not a single byte of TS2068 memory is used. Virtually all TS2068 programs run
from the disk without modifications.
The disk drives are the latest in 3" micro floppy technology, giving 160K of storage on
each side of a standard 3" micro—floppy diskette providing 320K of storage per disk.
As an added feature, the controller also has two RS—232c Serial Communications ports
which can be used with any serial peripheral. An LLIST, LPRINT iat ‘program is
included to use a serial printer with these ports from BASIC.
The ZEBRA FDD Disk Drive Systems comes complete with: One 3" Disk Drive,
ZEBRA Disk Controller, ZEBRA TS2068 Interface, ZEBRA Power Supply, T.O.S. System
Disk, Comprehensive Users’ Manual, All Cables, and the ZEBRA 90—Day Warranty
The ZEBRA FDD System is in stock and available for immediate shipment! Order
now, and add the speed and versatility of Disk Storage to your TS2068!

Do you have some spare equipment you would like to sell? Do you have a program that you
have written, and would like to sell copies? Maybe you are looking for something hard
to find. Place an ad in THE CLASSIFIEDS! Subscribers can place one free personal ad in
each issue. Ad size is 32 columns wide (like 2040’paper) and maximum of six lines. For
additional lines- $3 each. NON-SUBSCRIBERS and DEALERS: $4 a line. DEADLINE FOR ALL

For those of you with a TS-2068
computer and a TS-2040 printer

word processing. I have a

giving away. Called "RonsTEd",
it offers 4 type fonts and pro-
